The dichotomy between mental and physical is a false dichotomy.
   It's all physical, although perhaps not all measurable by us.
   Just what we're capable of. Even our conceptualizations are
   physical in nature, just faster engines with fewer constraints
   like gravity holding our "fllights of fancy" back. It's why we
   can always conceive far faster than we can build, even with
   regards to things we cannot ever build, because of some stupid
   "laws of nature" getting in the way in meat-space
